- 7 SHUTTLE GUAR Filed Aug. 25, 1944 JNVENTORS array/7 Patented Mar. 19, 1946 SHUTTLE GUARD I George A. Gill and Arrie Gill, Mexla, Tex. H Y Application August 25, 1944, Serial N 551,197 I 5 Claims. (Cl.139193) This invention relates to weaving looms and it has particular reference to shuttle guards for such looms. i

The principal object of the invention is to provide a shuttle guard adaptable to all types of looms and which consists of an open frame, hinged along one edge to the reed cap of a loom to overlie the sley and to hold the shuttle within restricted limits should it escape from the shuttle race, and to thereby minimize the likelihood of injury to an operator of the loom by a flying shuttle.

Another object of the invention is to provide a shuttle guard which is constructed to be raised so thatit will not interfere with the drawing of threads through the reed and further, it will automatically return to operative position upon startingof the loom.

Still another object of the invention is to provide a shuttle guard for looms, having means for supporting the frame in operative position in rela tion to the shuttle race; means for latching the frame in such position; spring means for thrustingthe frame into operative relationship with the latching means and means for limiting the displacement of the frame under the influence of said spring means. 7 r v With the foregoing objects as paramount, the invention has further reference to certain features of accomplishment which will become apparent as the description proceeds, taken in connection with the accompanying drawing wherein:

Figure l is a perspective view of a shuttle guard constructed according to the present invention, shown in operative position.

Figure 2 is a similar view showing the guard in raised or inoperative position.

Figure 3 is a fragmentary front elevational view of the guard exemplifying longitudinal displacement of the frame in the latching operation, and

Figure 4 is a view of the guard in vertical sec tion, shown attached to the reed cap of a loom.

Continuing with a more detailed description of the drawing, reference numeral l denotes the reed cap of a conventional weaving loom, the latter being more or less diagrammatically shown in the fragmentary side elevational view in Figure 4. Afiixed by screws l2- to the reed cap I0 is a pair of spaced apart L-shaped brackets l3, between which extends a tubular mounting M for the guard frame, to be presently described. A rod l5 extends axially through the member l4 and its ends protrude through apertures in the mounting brackets It. It is of course immaterial whether the tubular member turns on the rod 15 or the latter turns in the brackets l3, so long as the frame is capable .of hinging action irrrelationito the reed cap I0. .55. :1

The guard frame is made up of an outer-rod 16, whose ends are'bent inwardly, thence outwardly in parallel relation to the bodyof the rod andiare extended into apertures in relatively parallel straps I1, welded or otherwise secured to the-ends of the tubular member'M. The ends ofthe-gouter rod I 6 are threaded and nuts l8 applied thereto to hold the same in secure relation to the straps An intermediate rod l9 lies between and parallel to the outer rod l6 and tubularmounting l4 and has its ends turned inwardly and-weldedto the tubular mounting I l.- Amxed to and disposed {in transverse relation to the rods l 6' and i9 andJthe tubular member M are reinforcing straps 20., II

A plurality of guard supporting brackets 2 lfa're mounted in spaced relationship along .theputer face of the reed cap it! behind thetubular frame mounting l4 and these brackets extend downs wardly and outwardly at "the required T angle",'.fas

shown. On the lower end of each of theseflbrackets there is formed or providedsubstanti'ally ..U- shaped retainers or'slip latches 22. It willbefob served that these latches aresituated 'between the outer and intermediate rods of the framejwhen the latter is operatively disposed onth'e brackets 2| and further, that the loops of the'latches are elevated above the common plane of the straps 20 when the frame is in this position. In being so disposed, the latche 22 may receive the straps 20 when the frame is first lowered and then moved laterally towards the latches, as suggested in broken lines in Figure 3.

To move the frame laterally, as mentioned above, a compression spring 23 is mounted on the rod 15 at one end, between a strap l1 and a mounting bracket l3 so that a constant force will be applied thereby against one end of the tubular mounting member 14 to thrust the frame into latching position.

In order that the spring 23 will be operative to displace the frame only in the lowered position of the latter, a guide member 24 is provided on the intermediate frame supporting bracket 2! and consists simply of loop formed by turning an extended end of the bracket downwardly towards the body thereof. When the frame is in elevated position an edge of the intermediate strap 28 thereof will bear against an edge of the guide 24 to hold the frame against the action of the spring 23. However, since the lower part of the guide loop 24 is open, it will admit the intermediate strap 20 in the lowered position of the frame so that the latter may move to align the several 4, in which position it remains until it is manually.

returned to operative position or if the ope rator neglects to perform this act before starting the loom, the action of the lay will automatically drop the guard, whereupon the spring 23 will thrust the same into latched position after thefframe has passed out'of the influence of the; I g uide 24.

Manifestly, the construction ass'hown and described is capable of some modification and such modification as may beconstruedto'fall within the scope and meaning of the appended claims is also considered to be withinthe spirit and intent of' the invention. 1

What is claimed is: i

l. A-shuttle guard including in combination with the reed cap of a loom, an open frame co extensive with the reed of said loom, a tubular mounting member along one side of said frame, a rod extending through said member','-pivotally suspended at its endsfrom said reed cap and on which said tubular mounting is capable er rotative and longitudinalmovementa series of 'supporting straps aillxed to and depending; fromsaid reed cap, each having a latch uns lowerend,

means carried by said frame for engagement with said latches, spring means for urging. saidframe longitudinally to efiect said engagement and means for limiting longitudinal movement of said frame in raised position thereof.

2. A'shuttle guard for looms including in combination with the reed cap of. a loom, an open frame adapted to operatively overlie the reed of said loom, a tubular mounting member, a hinge rod extending through said member having its a series of angular supports therefor, each having a latch at its lower end at right angles to the "axis thereof receiving a part of said frame in lowered position thereof, spring means imposing 'a continuous pressure on said frame in one dir'ection, -t0'effsectengagement thereof with said latches-and means carried by an intermediate support for holding said frame against lateral movement in. raised position thereof.

4. A shuttle guard for looms comprising a frame rotatably suspended from and coextensive with thereed cap of a loom and capable of limited lateral displacement, a series of angular supports depending from said reed cap having latches on their lower ends at right angles to their axes and engageable with parts of said frame in lowered position of the latter and a loop carriedby an intermediate supporting member for resisting the action of said spring means'in raised position of said frame. Y

5. A shuttle guard-for looms comprising an open frame hingedly connected to the reed cap of a loom and capable of limited lateral displacement, supporting straps for the lower edge of said frame having open latches at right angles to their axes for receiving parts of said frame, spring means urging said frame into operative relationship with said latches and a loop on an intermediate strap for resisting the action of said spring means in raisedposition of said frame but ineffective to prevent automatic lowering of said frame upon the starting ofsaid loom.
